The Occupational Safety and Health Administration (OSHA) is initiating rulemaking to protect indoor and outdoor workers from hazardous heat and is issuing Advance Notice of Proposed Rulemaking (ANPRM) tomorrow, October 27, 2021. The ANPRM is currently up for public inspection and is accessible here.  OSHA is interested in obtaining additional information about the extent and nature of hazardous heat in the workplace, and the nature and effectiveness of interventions and controls used to prevent heat-related injury and illness. The ANPRM provides an overview of the problem of heat stress in the workplace and of measures that have been taken to prevent it, and seeks information on issues that OSHA can consider in developing the standard, including the scope of the standard and the types of controls that might be required.

Beginning October 27, 2021, submit comments at, the Federal e-Rulemaking Portal, and refer to Docket No. OSHA-2021-0009.  All comments must be submitted by Dec. 27, 2021. For more information, please see OSHA’s News Release and Federal Register Notice.
